SUBMARINE NOISE TREATMENT SYSTEM AND METHOD THEREOF

摘要

Disclosed are a submarine noise treatment system and a method thereof, which can significantly reduce underwater radiating noise caused by a propeller of a submarine with an active noise control method while considering a noise characteristic. According to an aspect of the present invention, provided is the submarine noise treatment system which comprises: a hydro-phone receiving a noise signal of a propeller; a control unit receiving the noise signal of the propeller received from the hydro-phone to generate a complementary signal; and a transmitter receiving the transmitter signal generated in the control unit to be transmitted to the propeller.
